Ok I have a Motorola Atrix HD running Cyanogenmod 10.1.3 and using the EB40 battery.
1. I would like to know what charger I should be using, I have the 850mA motorola charger that came with my phone, a 1amp pantech charger, a ONN 1.2amp charger and a 1.5amp off brand charger. Also how long should this battery take to charge?
2. I would like any tips or tricks to extend my battery life, my longest charge yet has lasted 26 hours of heavy use (im also running Juice Defender Ultimate) and I keep seeing people talking about getting 3-3 and a half days out of one charge.
3. Is there anyway to make my built in battery meter more accurate it doesnt seem to be reading this battery properly
On a side note, I accidently deep discharged my EB40 when i was running the initial charge out, and it was plugged and unplugged several times trying to get the phone to power back on, Im wondering if i damaged my battery and if so is there a way to fix it?
Sorry for the extremely long question any help would be greatly appreciated.

1. AHD could only pull 1A max. Beside good charger, you also need a good usb cable so that the power does not lost in transit. Install CurrentWidget to check how much power does your phone get while charging.
2. Minimum screen brightness, auto on/off data connection (LeanData app), undervolting? Battery consumption differs from phone to phone depending on how you use the phone, how good is your telco signal etc.
3. Perhaps you need to flash another rom? I'm on CM11 KitKat and the reading is fine. But battery life is not as good as stock JellyBean rom.
4. If your phone is dead after fully discharge, just leave it plugged in. after a while it will come to life.

1.So the cable that came with the 1A pantech charger would be fine? what are the effects of using a small or larger charger? say the factory .85A? longer charge times?
2. Juice defender controls my screen brightness at roughly 40% normally (I have good eyes) data shuts off with screen unless traffic exceeds 100kb/s, undervolting? lots of social networking and texting, music player (rocket player), and a playing a power hungry game, 1-3 bars at home depending on were i put my phone, 4-5 bars else were
3. Is that stable or nightly? I only run stable roms due to my phone being my only source of internet and i have no back up phone
4. Good to know thanks :laugh:
Also on a 1A charger with quality cable CurrentWidget should be showing 1A(or 1000mA)? and were CurrentWidget shows battery current draw what is considered high?
sorry for all the question im kind of a noob to modding my phone i ran cyanogen mod on my OG Droid but never did any real modding on it phone ran faster and battery life actually increased, same on my AHD my battery life increased after flashing to cyanogenmod 10.1.3 i gained approx 3 hours over stock jellybean

Wow that LeanData app is amazing, It's a shame that can't get the EB40 battery because It couldn't ship to my country so I need to live with the EB20 one.
Juice Defender Ultimate controls Data on/off Sync Screen brightness and timeout sound profiles based on schedules, bluetooth and cpu governer and clock speed if your rooted theres also controls for gps and wifi but i never uses those, i paid like $7 for it but i think it was well worth it on EB20 and stock jellybean i was averaging 10-11 hours of heavy use which was way better than my out the box 6-7 when i flashed to cyanogenmod and ran that with juice defender it increased to 13-16 hours, after adding the EB40 battery my shortest charge has been 18.5 hours, i was realy hoping to hit the 30 hour mark with all the people talking about going 3 and a half days on 1 charge

1. EB40 is rated at 3200mAh (miliamp per hour). so in theory, a 1A charger will take 3.2 hours to fully charge it. a 2.1A charger will still take 3.2 hours. 0.85A charger will definitely take longer time. do correct me on this. and btw, AHD has the qualcomm quick charging feature built in. I'm guessing 3-4 hours to fully charge this phone from 0-100%.
2. Keep using JD if it already improves the battery life. when the phone gets 1-3 bars or in a place with low signal coverage, it will draw more power to get the coverage.
3. I think most KitKat rom based on the latest CM11 release are quite stable. you can read about them in the development threads.

Hi all,
I just wanted to tell my opninion about the standard (900mAh) battery.
I heard a lot of people complaining about the battery, I also complained about the battery. But that was only the first week when I got the phone. After a week or 2 the battery became better and better, every time I charged it up. Now I use the phone 3 days without charging , compared to the 1 day I could use the battery in the beginning, 3 days is very good. Things what I do in those 3 days are: Internet (umts, hspda), Reading RRS feeds, taking pictures, listening music. So the battery is quite good. And I am happy now!!
Unlike the good battery, I am going to buy a new battery (1350 mAh) Imagine how good it then will be, then I can use even more like 5 days.
I just gave my opninion because, before I bought the Diamond, I heard rumors about the battery, that was almost a reason for me not to buy the Diamond. Still I bought it, and I can't confirm these rumors.
THE BATTERY IS PERFECT, and the phone is great too (especcially with the v1.93 rom)
So don't listen to those rumors, and give your own opninion, I give this phone a 9!!
I have had my diamond a week, and i found that the battery would be flat before i got in from work (8:00-5:00) and thats with very moderate use.
Last time I charged it up, I didnt use the charger that came with it, but instead used a standard wall mains to usb charger (came with a blue tooth gps) and its now on its second day, and it has only lost 3 cells on the power info screen.
have been using the phone more than normal only thing i have done different is install the tweaked com.manager to turn 3g off (dont get 3g in the are im at any way) and it seems to be great now.
where did you find this tweaked manager?

just use advaced configuration tool. Go to Options, Comm manager and add '3g' to the tick boxes.
I've made a few tweaks with Schaps and TF3Dconfig and my battery has excellent life now. I think it does take a few days of charging and discharging to settle down but I can now go days with reasonable use
In my opinion it also depends on WHAT you use to charge up your battery. I mean, whether you use the stock charger, or 3rd party charger.
I bought a 3rd party charger (http://www.momax.net/products_detail.php?cid=2&scid=1523&brandcat=82&pid=11134) and the output is only 400mA, when compare to the stock charge (where the output is 1A), even thought both are fully charged, I observe that the one using stock charge, can last longer than the one charged by the momax one.
Anyone has the same experience?
I already posted my thoughts.
My MDA lasts longer when charged with the stock charger (5V , 1A) as opposed to charging from my PCs USB port (5V, 0.5A)
Thank you for confirming what I was experiencing.
Yep same here, the battery last around 2-3 days. Turning of around 12pm and back on around 8am.
And yes charging form the outlet takes less time and seems to give a better more solid charge.
And yes the tweaks help very much.
Hey guys we are just getting to know our Jewel.
Shes a friendly gal!!!

I just watch one movie in Coreplayer and the battery becomes half empty. The battery is a joke. Sorry, I love this phone, but HTC really dropped the ball on the battery.

Another thing with ion-lit bats is that they require very controlled charge and that explains a lot of the problems experienced. I also believe the initial charging is important to respect. I charged mine for a full day initially, and noticed that it used all night for charging for a while (even the indicator was on full).
Today it was used for a few calls, had it on BT sync with my PC for a couple of hours, and used iGO GPS for 20 min, still leaving it 3/4 full. I could wish for more battery capacity - one week would be nice - but as long I only need charging at night I personally see no major issue. I have an extra battery or two as I tend to use the phine as MP3 player on long haul flights which I certainally prefer to the thicker backcover and the 1800 mAh battery.
I know those Pocket PC devices drain their power very very quickly, but when I wifi for let's say about 5 minutes on some websites, my power is drained like 10 percent maybe. Is that extreme or 'normal' for the kaiser?
On the other hand I must admit that when I do nothing with my kaiser it can last very long without recharching.
Which rom and radio are you using? These devices are not exactly renowned for their great battery life (the cost of 3g and hsdpa), but there are ways to optimize them...
PDACORNERultimate. But I also used a HTC P4350 earlier, and it was all the same with the battery life , just wondering how I can measure what battery is better because I have 2 tytnII's until tonight, so I was wondering how I can measure what the best one is .
ALL batteries lose the ability to keep a charge as they get older. Any battery over a year old should be highly suspect.
Get the Tytn II that appears newer, then get a BRAND NEW battery for it

A new battery cured my fast discharge problem. At the time Amazon had the best price on batteries.
I've observed with my TyTnII (1yr old) that the battery drains faster from 100% to 70%. However, it retains charge from 70% to 0% for a longer time.

A 10% change on the meter means nothing. To evaluate your battery life/drain, start with a fully charged battery and run it down completely until the PDA switches off.
As said above, the percentage reading is approximate and won't always go down in a linear way. It can go down from 100% to 30% in one hour, then take 3 more to go down to 0.
I think you are using the wrong charger. The charger u are using is nog strong enough. I had the same problem. You need the original charger.
I always leave my phone on the charger over night. I hadn't even thought about it until today, but I was reading a thread and it got me thinking that my short battery life may be because I charge over night. Could this be true?

good question..
well if you are like me, I only charge when I get home and more times than not I am going to bed. So I really don't feel like waking up just to take it off the charger and then let it sit draining battery while I go back to bed. I just leave it till I am up and ready to leave for the day. With my Cappy it last only about 12 hours anyway since it was new so I am not sure leaving it charging over night is that bad of a thing. I am however interested to know the scoop of how this might effect the overall life of the battery.
I don't think it's hurting battery life. On other threads with people asking why unplugging often shows between 95 - 100% charge even if the phone was left on the charger a long time. The answer given was that the charging software will purposely float between these ranges to prevent overcharging. So I think it's okay. And I've pretty much always left my phones charging all night - not just the Cappy - and never noticed any degredation in battery life or longevity.
When your phone is being used (not charging), li-ion batteries carries the - current to the + current, and when you are charging the phone, a external source (an outlet; your charger) applies a higher voltage than the battery operates at, but the same polarity, forcing the current to turn around and pass through the opposite direction (+ to -, instead of - to + like above).
Saying that, each "cell" in the battery has a "voltage limit"[per cell], when that limit is reached, the battery stops charging. Most cell-phone / PDA Li-Ion batteries stop charging at 2.7-3V. And of course, cells also have a inner clock, but this isn't exactly a new concept. All electrical sources have internal resistances, which build up over time, and it reduces the maximum capacity of each Cell, which in turn reduces the batteries overall capacity.
The battery won't kill itself, we're smarter than that. To put this for bed once and for all, it wouldn't matter if you were using the Li-ion battery or not; even if they sit on a shelf unused, internal resistances come with age.
So no, it won't kill your battery. The only things that can speed up the death of your battery is heat. My estimate, is our batteries will lose around 15-20% Maximum Capacity / YR. It's pretty much the average for cell phones.

I always put it on charge when I sleep at night like 11/12, and pull it out for a second or two when my first alarm comes up (~1 hour before I wake up) and put it back on charge immediately to top up, and pull it out when I am out of bed (~8). Been doing this since I got the phone. And I still have ~3.5 hours display time (with active transfer the whole time) and ~1 hour talk time, with ~18 hours standby.
In short, all our cell phones cut off charge when they are full. So it shouldn't matter.
What kills battery is heat. So keep it charged in an open area. If u feel the phone hot after charge, try taking off its case, if any. Keep the battery cool, and u should be good, even if u leave ur phone on charger all night.
Awesome, thanks for the help everybody. However, I heard something about charging overnight while undervolted killing the phone... anyone know about this?

My battery never charges above ~76% when plugged in. After rebooting however, it is very much at 100% and lasts for a good amount of time. This is not necessarily a question, but I wonder if others are experiencing this too and if there is a fix? Read below.
I noticed that my battery life got very bad after installing custom roms. I also found out that this happened because I sometimes kept the phone plugged in while flashing, something that totally screws up the battery reading. So, I followed this guide to calibrate my battery and it worked.
Now, whenever the phone is plugged in it NEVER goes to 100% when charging. Maybe 80% if leaving it for a while (10 hours overnight). I'm worried about frying the battery. Is there a fix?
It is only a matter of presentation. It actually doesn't mean your batt is broken. Plug it and charge it overnight. Then discharge only for few percent and plug it back in. It should go to 100%.

Thanks, I'll give it a try.
What I'm concerned about is if the phone "thinks" the battery isn't recharged and keeps squeezing juice into it when in fact it is full (which a reboot will show)? That's not good for the battery. It should go into trickle charge after reaching 100%..
The process described in the desire forum is also known as formatting the battery. In fact most of battery manufacturers (lithium battery manufacturers) recommend doing this in a slightly different way:
Before first use:
1.) Before powering the device on, plug it in and let it charge until the LED is green (fully charged)
2.) Then take the battery out of the device and wait an hour (to make sure all the chemical processes in the battery are as idle as possible)
3.) Then plug it back in, while still off and let it charge untill green LED
4.) use the device....
You can practice this slightly modified with first step being:
Discharge the battery (by normal use)until only few percent are left (1 - 5 % are OK)
I've done these steps with my Mugen extended battery and I was getting around 4 - 5 days on Legend, now I'm getting 2 - 3 days on Desire S, but the ROM isn't very optimized yet, I believe it will be better in time...
Just one thing... Why is this in Development!?
No Idea.....
can mods move this?

Definitely did not solve it but at least the battery performance is ok. It just stays at 78% for a few hours drops from there. Very weird but as long as the battery doesn't get broken I guess it's ok.
Do you have some 3rd party battery installed in your Legend? I have one 1,5 Ah in mine and it is acting the same way. It doesn't bother me too much coz it was cheap... it lasts 48 hrs with data always on and moderate usage. I noticed this that when I charge it overnight and it reaches 80%, unplugging it stays at 80% for several hrs and just after it starts dropping if I plug it again, meter reaches 100%. It's weird but as I said I can live with that
I've got exactly the same issue with stock 2.2 ROM. I've never rooted or CM my phone; I was wondering if CM would do it, but doesn't look like it.
android forums /htc-legend/265545-battery-doesnt-fully-charge.html
(sorry, I can't post links; maybe an admin can fix the link for me?
This seems to indicate it's a phone hardware fault and requires a new Legend to fix! My big worry is, as stated, that the charging light never goes green; therefore is pumping lots of power into a potentially full battery.
H, since I updated from miui 10 to miui 11 and even now that I have miui 12 I have noticed that the battery doesn't last as long as before. I state that since I purchased the phone (July 2019) I have always charged the battery in the best way trying to never go below 20% and trying not to go beyond 80% so I don't think a battery can lose more than 30% of its real capacity in less than a year of life. Starting to investigate I found that the battery does not charge at its real capacity i.e. 3300 mAh but at around 2200/2300 mAh. To verify all this I have carried out several tests and the easiest way to verify it is to look at the battery characteristics through the AIDA64 app (screenshot below). From these tests it seems that the device limits the real battery capacity by not allowing it to be charged to its maximum capacity. A reply to what I wrote can be found by looking at some system files that are located in /sys/class/power_supply/battery. In particular, looking at the file called charge_full (screenshot below) you can see how the value of the file is much lower than the real battery capacity. I hope someone more competent than I can understand how to solve this hateful problem and I also invite you to check the value to try to better understand the cause of this problem.
I'm using miuimix 12.0.2 stable and the capacity is not 3300, either.

I know that batteries won't be forever and are always decreasing during the year but I think Xiaomi do a good job. I have some devices from 4 years ago and they reduced their batteries just a little. In the case of Mi 9 I have it since March 2019 and my battery still being the same. I charge it from 10-25% to 100% just some times I charge it until 80-90%, maybe every month I let it to 0% I wait for a while and charge it again to 100%.

From the photo you posted it doesn't seem that your battery is fully charged .. we have done other research and we have discovered that most likely Xiaomi has inserted in the kernel a sort of programmed obsolescence on the battery.
Can you disclose some of the research you done on the kernel it seems interesting. I have checked with Aida64 my battery before and it never charges to 3300 even if you leave the phone plugged in the value will keep increasing but once you plug it out it drops...still getting about 5 hrs sot so not bad...I wonder if you change that value in the full charger screen you posted what will happen?
"From these tests it seems that the device limits the real battery capacity by not allowing it to be charged to its maximum capacity. "
Actually it's better for battery life longterm to keep the device in the middle - never 0, never 100
I've certainly lost no battery life in the year + I've had the Mi 9
You are doing a good job of using the phone in the 20 to 80% range. But do you charge it at the lowest possible temperature? Temperature is a battery's worst enemy. Wireless charging is a joke. It's a glued heater in the battery.
I for instance, almost all the times charge it in front a mini fan. With this I can charge it 5ºC below normal temp charge.
And like @cezikos said, use quickcharge only on emergencies. Use at max a 1.5Amps charger. Quick charge is a marketing thing. The chemistry of the batteries are almost the same in this 10 years.
Mi mi9 have one year and the battery is 100%.
The important thing that you should precise is a type of charger that you are using. Do you use Quick Charge? If Yes, then battery capacity will be dramatically degrated. I use 5V 0.5-1.5A charger, it depends how fast I need to charge the Phone.
The next thing is a battery temperature, not Only while charging the Phone but also when you are using it. I`m using CPU Monitor and it's overlay to see the battery temp, you can also configure alerts when battery is starting to overheat.
Heavy Gaming decreases the life of the battery, there are a lot of variables that you have to cobsider, not only "programmed obsolescence"
I had the same problem. Hopefully the battery could make 3 hours of screen, the strange thing was that suddenly it began to last very little, and I was with that problem for a couple of weeks, so I decided to calibrate the battery hoping to have some results and now the battery lasted again approximately 7 hours of screen. Try to make the battery run out from 100% to 0%. The system will not let you start because it calculates that it has no battery, so what I did was leave it in recovery mode and with the screen always active, until it turns off completely, then with a 5V 1A charger. With the phone turned off, charge it until it reaches 100%. I did it three times and the battery was back to the way it was before. You could try to do the same and I hope you can solve that problem.
Sorry for bad English
I tested, I put the phone to play videos until it turned off. In 1% I cleared battery stats.
Then plugged the charger and entered the TWRP and unplugged. Put the backlight to maximum, and the phone stayed on more than an hour!
Then I plugged the charger 1.5A and let it charge to max.
It worked, now the phone has a steady discharge, not discharge 100% to 80 in an hour.
I will do this procedure from time to time. not the best for the battery, but is needed in mi9...
It's an absurd that this problem exists in 2020, my galaxy S2 don't have such harsh problems with something so simple and basic like battery management!
Battery on my Mi9 (mildly used in one year) lost 500 mAh.
Confirmed, with this trick, in doing it ONE time, I have the phone running well again, more than 8h screen on.
0.5 discharge in sleep.

Thanks! I just don't know how to clean the battery status...
You will need root.
Then are several apps that can do it. Like l speed or adiutor.
And now again confirming, in one month the phone is completely lost regarding battery again, just 3h SOT from 80 to 20. There's some pretty **** up code regarding battery in xiaomi android.
I have no problems at all using it since release.
newest xiaomi eu.
I also have problems with battery drain...
Hello guys, just want to share with you a little trick that just helped me get better SoT. First of all, I just want to mention that I'm on the newest xiaomi.eu rom (20.8.13) and that AccuBattery is showing that my battery is at 2500mAh estimated capacity. (That might be different in reality, because it's only after one charging, so don't believe it that much). Lately I noticed a significant drain while the phone was idle (screen turned off). It was draining like 1-2% every hour and I could barely get over 5h SoT. So I investigated a little bit, and found a solution on reddit. The thing was that I had many apps on autostart. If you want to check them and turn it off then open Settings > type 'autostart' in the search bar > open it > 3 dots > show system apps > turn off every unnecessary app that you think don't need that option. I turned off every app, except: Gmail, GPay, Google Photos, Clock, Calendar, Bank app, Weather app and the app called 'safety system addon' - it might be called different because I'm not on english language on my phone. I left them on just in case to have notifications/synchronization, though i don't know if it's necessary. After that there was almost 0% idle drain over the day. Now I'm on 5h4m SoT and still have 25% of battery left. The result might be even better, cause I did this trick just today while my phone was on 90-85%.
Give it guys a try, hope it will improve your daily experience with Mi 9.
P.S. Let me know guys If I could turn off the before mentioned apps and still get notifications and sync from them.
Mine reports 2800mah, debloated with Szaki tool all autostart apps disabled also did factory reset after miui12 update.
Really sad how bad miui12 has turned for me. Im having way worse battery life compared to miui11 the idle is mostly the same its just the battery doesn't last as it used to last with miui11.

Then I plugged the charger 1.5A and let it charge to max.
It worked, now the phone has a steady discharge, not discharge 100% to 80 in an hour.
I will do this procedure from time to time. not the best for the battery, but is needed in mi9...
It's an absurd that this problem exists in 2020, my galaxy S2 don't have such harsh problems with something so simple and basic like battery management!

I can confirm this. AIDA64 said my battery was at 2550mah capacity when fully charged. I followed this procedure and now after being fully charged, it says 3125 mah, which is much better.
I'm curious about the screen on time now. Me happy. Thanks!
